Also, the behavior of Timulla species, and first report ofT. intermissa in the Brazilian Pantanal was reported. Keywords: parasitoidism, Pantanal, host report, velvet ant, Mutillini.

Here we observed that females of E. Mutillidae are wasps that parasitize mature larvae or pre-pupae of fulsvofasciata built their nests in open areas with sandy soil, in a other insects, especially other aculeate Hymenoptera (Brothers et al. high concentration of nests: 83% were complete and 17% under 2000). Among the Hymenoptera, their known hosts are Vespidae construction in five plots of 1m2. Timulla females were observed (Polistinae, Eumeninae), seveval Halictinae and Bombinae (Apidae) in this area, entering and staying there for about five minutes in the (Brothers et al. 2000), Sphecidae and Crabronidae (Quintero & complete nests and in those under construction. Cambra 1996, Cambra & Quintero 1993). About 2-3% of Mutillidae Our study shows the first record ofE. fulvofasciata as a potential hosts are known in the world (Brothers 2006). In the Neotropical host of Timulla species. Species of Timulla have already been region, there were an increasing number of records in recent years recorded parasitizing other hymenopterans: Solenopsis invicta Buren, (e.g. Mickel 1969, Yanega 1994, Cunha 2004, Lima et al. 2008, 1972 (Formicidae) (Brothers et al. 2000), Epicharis sp. (Apidae) Bergamaschi et al. 2010, 2011, 2012). (Rocha-Filho et al. 2008) and species of Sphecidae and Eumeninae The mutillid Timulla Ashmead includes species from Africa, (Vespidae) (Quintero & Cambra 1996, Cambra & Quintero 1993). Asia, Australia and islands of Pacific Ocean (Mickel 1938). One Other species of Exomalopis have already been recorded as hosts of hundred sixty-one Neotropical species were described and little is mutillids. Exomalopsis solani Cockerell, 1896, was parasitized by known about their biology and hosts (Cambra & Quintero 1993). Pseudomethoca bethae Krombein, 1992 in Arizona and New Mexico, Most Timulla species have restricted geographic distribution (Mickel USA (Norden et al. 1994) and Horcomutilla sp. in Mato Grosso do 1938) and show high level of host specificity (Wilson 2010). Twenty- Sul, Brazil (Lima et al. 2008). seven Timulla species were described in Brazil (Mickel 1938), with The nests were monitored over six months, but due to Pantanal 12 species recorded in Mato Grosso do Sul state. There is little flood pulses, nest openings were destroyed and the emergence of hosts information on Neotropical Timulla hosts, having records only for and parasitoids could not be monitored, and, thus, it has not been T. centroamericana (Dalla Torre, 1897) (Quintero & Cambra 1996), possible to obtain data on the frequency of parasitism for the species. and T. pictoria Mickel, 1938 (Rocha-Filho et al. 2008). The Timulla The considerable number of Timulla seen upon entering bee nests over fauna is scarcely known in Neotropical region, particularly in the a short time interval indicates that the use of E. fulsvofasciata nests Pantanal, the biggest wetland in the world where only 7 species were in the Pantanal region is not accidental. We consider the behavior recorded (Cresson 1902, Mickel 1938, Aranda & Catian 2008). In this paper we reported the activity of two species of Timulla parasitizing of Timulla females in the nests of E. fulsvofasciata as an evidence nests of Exomalopsis fulvofasciata (Smith, 1879) and a new record of parasitism, however future research is also necessary to better for T. intermissa (Gerstaecker, 1958) in the Brazilian Pantanal. understand the ecological relationships involving these species.
